Trump Campaign Fires Back At ‘Self-Righteous’ Zuckerberg

Donald Trump’s campaign staff have criticized Facebookfb supremo Mark Zuckerberg after he took a thinly veiled swipe at their candidate over his politics of fear.

“I think I’ll take Mark Zuckerberg seriously when he gives up all of his private security, moves out of his posh neighborhood and comes live in a modest neighborhood near a border town, and then I’m sure his attitude would change,” Trump spokeswoman Katrina Pierson told CNBC.

Zuckerberg this week used a keynote address at Facebook’s F8 developer conference to decry current political rhetoric against immigration and globalization. He called for politicians to have “the courage to see that the path forward is to bring people together, not push people apart, to connect more, not less.”

“I hear fearful voices calling for building walls and distancing people they label as others, for blocking free expression, for slowing immigration, reducing trade and, in some cases around the world, even cutting access to the Internet,” Zuckerberg said.

While these don’t all apply solely to Trump — Ted Cruz has also called for mass deportations and a wall on the U.S.-Mexico border — the sum of those parts certainly does add up to the Republican frontrunner.

Trump famously wants to build that wall on the border and get Mexico to pay for it, has threatened to bolster libel laws to retaliate against the media, has made proposals that would probably spark trade wars with Asian countries, and has even advocated “closing parts of the Internet” to fight Islamist extremism.

“Self-righteousness isn’t very proactive,” Pierson said on Wednesday, adding that Silicon Valley CEOs should “focus on innovation and jobs and their businesses, and let the politicians make their policies.”

“It’s great that we can have innovation in this country, but you should be able to do that without putting the lives of Americans at risk,” she said.

This isn’t the first spat between Trump and Zuckerberg. Last year Trump claimed at a debate he had never taken a shot at the Facebook chief over his enthusiasm for hiring foreign workers, before moderators had to point out that his own website showed he had done just that.

Facebook Messenger’s Product Chief Talks About His Love Of Chat Bots

Facebook introduced a grab bag of new products and tools on Tuesday at its annual developer conference including 360-degree video, animated profile photos, and a tool for easily signing into apps. One of its unveilings had been hotly anticipated for weeks: “chat bots,” or software that acts as a sort of human-like assistant that answers questions for Messenger users.

Facebook fb is only the latest company to join the chat bot craze after Telegram, Kik, and others. But Facebook Messenger’s 900 million users means that a huge number of users and outside developers will be eager to at least try these bots out.

For users, the chat bots can help with ordering services or products and receiving personalized news digests, among other things. For companies, they can help field customer questions and requests.

Whether the bots gain traction is another question, of course.

Facebook’s opening of its doors to bots from outside developers is a natural next step after it allowed businesses to access its Messenger app last year to communicate with customers on the service. Since then, the company says that one billion messages are sent between businesses and users every month.

Fortune took a few minutes to chat with Stan Chudnovsky, Facebook Messenger’s head of product at the company’s conference. The conversation has been edited and condensed for clarity.

Fortune: How long has the bot store been in the making?

Stan Chudnovsky: We started to experiment with that pretty much after F8 developer conference last year, and we experimented with a bunch of different approaches and tried to flesh it out and think about what would be best and what the API [a software tool that lets developers connect to the Messenger app] might look like and what are the capabilities that we would have to release for the developers to be happy and creative and that kind of stuff. So it’s been a while.

Where did it come from? Did you have a lot of demand for chat bots?

We just saw that the initial experiences that we released last year [when we let businesses exchange messages with customers] were working, and users love them, and businesses love them. We asked ourselves how do we make it scalable because what we’d done before required a lot of customization on both our part and the businesses’ part. And it also required customer service agents on the businesses’ side, so we’re like, “Okay, how do we help people automate as much of that as possible?” Once you start asking simple questions you simply arrive at fairly straightforward answers.

So how many bots do you expect to see over the next year?

We are hoping for thousands and thousands.

How do you intend to make money?

We’re going to play the same playbook we always play. In the sense we just want to see how the ecosystem develops, and then we’ll figure out how we want to play into that ecosystem. But genuinely, for us right now, it’s about providing as much value to our users as possible and everything else will follow.

Any guesses as to how you might end up making money?

Advertising. Because from a guesses perspective, I’ll give you a hint: The advertising business has been a very good business for Facebook so far, and we’re going to continue to focus on advertising.

What about M, [Facebook’s virtual assistant that uses bots and humans], and its relationship to the bots?

So we are working out how exactly it’s going to play out. One important thing to say here is that the Wit.ai team, the development team behind M, is the same team that is behind the bot engines that we released today. So we are taking a lot of what worked for us in our M playbook and making it available to everybody. And, how exactly one thing will work with another, we are still working it out.

But there are a bunch of experiences that you can imagine. For example, you might be with working with M, and M might call in the bot that might be most helpful to you for example and then that bot that M invites takes over.

Now the good news is that all the functionality, we’re going to experiment like we always do with the different approaches and see what our users like—the same playbook that we play with the bot platform.

The bot engine that you just opened today, what do you envision? Why did you open that piece first?

The reason why we released that piece is just because it makes it easy for developers to build bots not only for the Messenger platform, but also for other platforms that they prefer. And it gives everybody [both Facebook and outside developers] a lot of data to play with which is also very useful.

Does this open source sharing of tools part of the strategy? You want to make these tools available and see what people do and learn from each other?

Yeah. Definitely.

What about Instant Articles and publishers in general—what’s going on with Messenger and that right now?

You saw that two of the bots that we announced are with CNN and the Wall Street Journal and we’re pretty excited about those. One of the reasons why it’s such a good experience is because we are working through Instant Articles [Facebook’s own fast-loading format for displaying news articles inside its apps].

For example, in the Wall Street Journal, you can subscribe to whatever topic you like, you can get notifications from them, you can get full articles, you can have basically a thread with the Wall Street Journal that is tailored to your needs. And it’s only going to be possible if everything happens fast and everything happens quickly and it’s fast and it’s a nice user experience and Instant Articles provide that.

We just know that users like Instant Articles and we want to make them available through Messenger as well, and bots seem the most natural way of making that possible.

How do you think these new experiences are going to affect the sharing or reading of news in the News Feed? Do you think it’s going to overtake it, how do you think that’s going to be?

We think it’s completely complimentary. It adds yet another venue for our news organization partners to distribute their content. We don’t see it as competing at all. It’s just very, very different.

In the News Feed, it’s more like discovery. What do you see there? You see the articles that [Facebook spokeswoman Jillian Stefanki], for example, liked and read yesterday and you say, “Oh, I like that topic, I’m going to read it.” And you tap on it and you go to Instant Articles and you read about topic A. And that might be a topic that you were not interested in before, but you now know about because you discovered it through Jillian.

In Messenger, the experience will be different where you decided which topics you want to hear about from particular news outlets. You design that bot to tailor to your needs. We see it as completely complimentary and completely an addition. If anything, we feel like it’s going to give you guys more eyeballs.

What is your favorite bot so far?

I like them all! It’s like asking me who is my favorite child. What is my favorite bot? It was a lot of work over the last two weeks to get them all to work because a lot of stuff was coming in at the last minute. So, I say we got the news bots to work first, so I was worried about them the least and for the longest, and so I like them.

Facebook Unveils Plans to Bring Internet to Both Cities and Rural Areas

Facebook revealed more details about its ambitious plans to bring the Internet to the rural world as well as metropolitan cities.

Speaking at Facebook’s annual coder conference in San Francisco on Wednesday, the company’s vice president of infrastructure engineering, Jay Parikh, outlined several new research projects from Facebook’s Connectivity Lab.

The Connectivity Lab is an in-house Facebook research unit supporting the social network’s Internet.org initiative meant to bring the Internet to places where Internet connectivity is scant.

The first initiative he detailed, named Project Aries, is a modified version of the types of cellular towers and base stations one might see while driving on the freeway. Parikh explained that in traditional radio communications, these stations and towers typically use one antennae in which “the amount of radio signal gets split up among everyone.”

With so many people hogging up the radio signal, the cell tower can become congested, which may cause you to “want to take your phone and chuck it out of your car,” Parikh quipped. To cut down on the congestion, the Facebook prototype system uses a type of advanced wireless technology called Massive MIMO, making it possible to cram more antennas into a radio station to help deliver signals.

In a Facebook blog post on Project Aries, Facebook noted this form of wireless technology has matured to the point that “many industrial base-station and device manufacturers worldwide” are exploring its use as well.

Prototype of Project Aries

The proof-of-concept project contains 96 antennas and custom software that Parikh said can deliver a very high rate of what’s known as spectral efficiency, which is used to measure the most amount of data that can be transmitted with the least amount of errors.

Parikh did not say where Facebook plans to test this system, but he believes that the project will help bring next-generation 5G wireless communications to rural areas.

The second project Parikh detailed, dubbed Terragraph, is a wireless system designed to blanket cities with Internet connectivity. Through so-called distribution nodes (resembling small, rectangular boxes) that can be attached to lamp posts and other pieces of city infrastructure, a Wi-Fi or cellular network can be maintained and offer the possibility to “replace fiber in these dense urban environments.”

A blog post about Terragraph further explained that the wireless system and related technology comes from an existing Wi-Fi standard known as WiGig, which Facebook engineers explained is “designed for consumer electronics, which allowed us to create nodes that are inexpensive relative to traditional telecom infrastructure.”

Additionally, the wireless system uses unlicensed spectrum, which don’t require permission from regulators to use, but is generally more unstable than licensed spectrum “because it gets absorbed in water and oxygen,” Parikh added. To improve the efficiency of the wireless system, Parikh said the company incorporated some of the advanced networking techniques Facebook uses in its massive data centers to ensure data continues to flow without interruption, regardless of failures.

“The system will recover where there are outages,” Parikh promised, regarding Terragraph.

Facebook is currently testing a prototype of Terragraph at its headquarters in Menlo Park, Calif. with plans to test it out in nearby San Jose as well. Parikh did not specify when the San Jose trial would commence, but the plan is to eventually expand it to other cities.

Additionally, Facebook wants to eventually open source the project and make it available for free as part of the company’s recently launched Telco Infra Project (TIP). Within this group, members have free access to hardware and software designs in order build custom cheaper and more efficient communications equipment. Current partners of that group include Deutsche Telekom, Nokia, and Intel intc.

As part of its Internet connection initiative, Facebook has previously detailed how it built a huge, solar-powered drone with the wingspan of a Boeing 737 that can stay up in the stratosphere and beam down the Internet to regions in India and other countries that may lack solid Internet connections.

Parikh did not give an update about where the drone project stands, but he instead turned his attention to two Internet connectivity research projects on the ground. While optimistic about the outcome of the new research projects, Parikh did warn that it won’t be easy as just turning on a switch.

Facebook Poaches Google Tech Wiz in Battle of Infrastructure Giants

Facebook has hired Regina Dugan away from Google to lead its new “Building 8” unit, a project that will aim to combine potentially mind-bending research with the more pragmatic world of product development.

The idea of Building 8—part of Facebook’s just-outlined 10-year plan—is to build stuff to better connect the world. While connecting people has always been Facebook’s mantra, the advent of billions of connected devices that comprise the Internet of things, adds a whole new dimension going forward. In the future, people will increasingly communicate with devices in addition to other people.

Building hardware for that mission will be a big chunk of Dugan’s job.

Dugan had led Google’s goog Advanced Technology and Projects (ATAP) effort. Before that, she was director of the Defense Advanced Research Projects Agency (DARPA).

In a statement, Facebook fb touted Dugan as “a proven leader with a long track record of building teams that deliver breakthroughs in research and product development.”

Menlo Park, Calif.-based Facebook fb, like Google, knows how to scale. It counts more than 1.4 billion active daily users for whom it must store and manage photos, videos, and lots and lots of posts.

Also like Google, it has pioneered innovative data center hardware and software. Facebook drove the creation of the Open Compute Project, for example.

Check out everything Facebook unveiled at F8:

The news of Dugan’s appointment follows barely a day after the opening of Facebook’s F8 Conference, during which company execs such as chief executive officer Mark Zuckerberg unveiled a world of bots and revealed its aforementioned 10-year plan.

Facebook’s CEO Talks About A Virtual And Augmented Future

Over the next 10 years, Facebook plans to push full force into artificial intelligence and virtual reality.

Currently, Facebook is known as a social network for posting photos, commenting to friends about bar hoping, and reading the news of the day. But over the next decade, CEO Mark Zuckerberg believes that advances in artificial intelligence and virtual reality will make the social network even more compelling.

In the future, users will be able to share 360-degree videos of their families and be presented with news stories they never knew they would be interested in but contain photos they may find fascinating, he explained.

Zuckerberg, speaking at his company’s annual developers conference in San Francisco on Tuesday, said that Facebook’s goal in advancing artificial intelligence technology is to “build systems that are better than people in perception.” These systems will recognize and explain objects in an image or understand speech when spoken to.

He said that Facebook’s photo-sharing app, Moments, “uses the best facial recognition system in the world” to understand human faces in pictures. Of course, Google and Microsoft, which both brag of similar image-recognition technology, would likely disagree.

Facebook’s image recognition technology has gotten so good that the company built a tool for the blind that can understand images in a picture and read them the contents of the image out loud.

Facebook eventually plans to incorporate it’s image recognition technologies into its news feed so that it will be able to show users news stories containing images most likely to grab their attention. Zuckerberg didn’t elaborate in more detail about how exactly this would work.

It’s possible that users who are normally uninterested in news about the Syrian refugee crisis but who happen to be lovers of photojournalism would be targeted with news articles that contain the type of dramatic photos Facebook believes they would read. The goal is to “show more interesting content” that users won’t even know they want until they see it, Zuckerberg said.

About virtual reality, Zuckerberg said the technology “has the potential to be the most social platform.” “You just feel like you are right there with another person,” he said.

When his daughter takes her first steps, Zuckerberg said he wants to capture the whole scene in 360-degree video so that friends and family can strap on VR headsets and “feel like they are in the same room with us.” He also showed a video of two people that are in different places playing games like Pong together in a virtual reality environment.

“This is a kind of social experience you can’t have on any existing platform today,” Zuckerberg said.

Although Facebook has previously said that it’s still the early days of virtual reality, it has been investing heavily in the technology in anticipation of a boom in VR content and 360-degree video files. For example, to help spur more people to shoot 360-degree video, Facebook unveiled its own camera and said it plans to make its design free for anyone to build.

And while he is betting that the recently released Oculus Rift VR headset will generate big sales, Zuckerberg believes that in the future, similar devices will be much smaller and resemble traditional glasses. Furthermore, he argued that they will incorporate both virtual reality and its close cousin, augmented reality technology.

Unlike virtual reality headsets, which surrounds a person in a full 3D interactive environment, an augmented reality headset, like Microsoft’s msft HoloLens, overlays 3D holographic images into a person’s field of view of the real world.

The virtual reality glasses of the future

In the future, people will be able to show photos to friends wearing hybrid VR and AR glasses, and expand those pictures in front of their friends’ faces, Zuckerberg explained.

“It will take a long time for us to make this work,” Zuckerberg acknowledged.

On Tuesday, the social network announced that iOS users will be able to also use short videos from partners like Instagram, Cinemagraph Pro from Fixel, MSQRD, Vine, lollicam, and BeautyPlus. Additionally, Facebook is making the software tools for this publicly available so that other developers can also take part.

And the move is not surprising: Every day, Facebook profile pictures get more than 4.5 billion views and nearly 30 million updates, according to the company. That means we’re about to see a lot of GIF-like silly profile photos.

Last month, Facebook acquired Masquerade, the company behind popular mobile app MSQRD for taking selfies and adding visual effects like celebrity hair dos and cartoons characters. The deal was an obvious move to help Facebook better compete with ephemeral messaging app Snapchat, whose various selfie decorating and animating tools are a huge hit with its users.

Looking at the bigger picture, video has become an increasing focus for Facebook, which is encouraging users and companies to upload video to its social network to compete against YouTube. During the company’s annual developer conference in San Francisco, Facebook product chief Chris Cox said that more than 70% of mobile Internet traffic is expected to be from video in a few years. In addition to uploading video, Facebook fb is also promoting live video broadcasting through Facebook Live, its rival to Twitter’s Periscope, among others. At its conference, the company said it’s releasing a tool to make it easier for developers to embed these live streams into their apps.

Facebook Just Built A 360-Degree Camera

Facebook is so certain that virtual reality and 360-degree video will become mainstream that it has built its own camera to capture 3D images.

But rather than selling the device, called the Facebook Surround 360, and software, the social network plans to make the designs publicly available for free later this summer on the coding repository service Github.

Facebook chief product officer Chris Cox said at Facebook’s annual developer conference in San Francisco on Tuesday that the company “set out to build the perfect 360 camera.” The goal was to create a camera that captured immersive video that required very little post processing for high quality images.

Grand Central Station Video Taken With New Facebook Camera

By making the camera designs publicly available, Facebook is trying to encourage the development of lower-cost cameras. Greater public adoption would translate into more immersive footage that would in turn give people more reason to buy Facebook’s Oculus Rift virtual reality headsets.

Cox said little about the actual hardware used to build the device, but said that it can record two hours of 360-degree video and that its image resolution is as high as 8K.

For more about Facebook and VR, watch:

In a blog post about the new camera, Facebook said that the video files can be viewed in VR headsets such as Oculus Rift and Samsung Gear VR. It’s not clear at this time if Facebook will make the files compatible with competing VR headsets from Sony, HTC, and others.

From the Facebook blog post:

We want others to join us in refining this technology. We know from experience that a broader community can move things forward faster than we can on our own.

Facebook Welcomes ‘Chat Bots’ to Its Messenger App

After opening up its chat app Messenger to businesses last year, Facebook is now letting them build bots for the service, said co-founder and CEO Mark Zuckerberg on Tuesday at the company’s annual developer conference F8 in San Francisco. Brands and companies will be able to build small artificial intelligence software programs that interact with Messenger users.

“Last year, Messenger was the fastest growing app, ahead of even Facebook, which was second,” boasted Zuckerberg, inciting a laugh from the audience. The Messenger app now has 900 million monthly active users, up from 800 million in January, the social network revealed last week. Currently, more than one billion messages are sent between businesses and users via the app, Facebook’s top brass added on Tuesday.

Over the last few months, Facebook has announced a string of partnerships with a handful of companies, including Uber, Lyft, and KLM Royal Dutch Airlines. Now, the social media brand counts more than 40 partners for Messenger, such as CNN, eBay, Walmart, Spring, the NBA, JackThreads, Zulily, Spotify, Zynga, and 1-800-Flowers, among others.

Through Messenger’s Send/Receive software tool, now available to developers, businesses can build bots that not only send and receive text, but also images, emoji, and other rich content such as product carousels to let users browser merchandise options from a retailer, for example.

For more from Facebook F8, watch:

“I can guarantee you’re going to spend a lot more money than you think,” quipped Facebook Messenger’s chief, David Marcus, said after an on-stage demo of shopping service Spring’s bot.

Other tools Facebook is releasing include a discovery engine, a customer matching feature powered by Twilio for enabling businesses to respond via Messenger to customers with phone numbers on record, and a bot engine for training them, powered by Wit.ai, a startup Facebook acquired last year.

Though it’s been greatly anticipated, Facebook is far from the first to introduce a chat bot store for its messaging app.

Last week, Kik unveiled one, and Telegram has had one since last year. On the enterprise side, workplace chat service Slack has had bots integrated into the communication hub for a while, while Microsoft MSFT recently unveiled a set of software tools to let developers built bots for its own services, like Skype and Cortana.

Moreover, Facebook shared that it has seen 40% year-over-year growth for the number of developers using its platform to built third-party apps, adding that more than 80% of the top apps made in countries like India, China, Brazil, Germany, and the United Kingdom are done so using Facebook’s tools.

For more from Facebook F8, watch:

Overall, developers across nearly 250 countries around the world are using Facebook’s platform.

As a point of comparison, Facebook had only 24 million users in 2007, the same year the first iPhone came out. Today, Facebook has approximately 1.59 billion users, and there are more than two billion smartphones around the world.

To further support its global community of developers, Facebook will release its software documentation in 16 languages with more to come, Liu promised.

He said that live streaming is more personal than a pre-recorded video, that celebrities who have signed on to stream live videos on Facebook’s social network are getting a bigger audience on Facebook than their own television shows. To popularize Facebook’s live video and ultimately gain more users, the company released a so-called API (application program interface) that will let coders build software around Facebook’s live video service.

In a demonstration of the new API, a drone flew on stage next to Zuckerberg while a big screen behind the CEO displayed live video of the conference that the drone was recording.
